Three of Rovio's monstrously popular games about foul-tempered fowl flock together in this compilation from ValuSoft Cosmi. As always, players load a variety of uniquely skilled birds into a slingshot and fire them at green, egg-stealing pigs in an attempt to knock the thieving swine off their pedestals, or crush them beneath falling debris. PC gamers guide the birds through hundreds of levels taken from the original Angry Birds, the outer-space adventure Angry Birds Space, and the holiday-themed "Angry Birds Seasons."
